1955 ''Live'' Commercial for Grape-Nuts cereal
An example of an "integrated commercial" from the 1950s, which meant including the cast of a series into the commercial, with them remaining in character, sometimes tied into the storyline of the episode. But there were only 3 commercials during the whole broadcast! Interestingly, Grape-Nuts doesn't contain nuts and doesn't contain grapes.
